Same problem here on 64 bit 7.10, Brother HL-5150D_series, quite frustrating though as this did *not* fail until a recent update and some hal/dbus updates I saw. Perhaps the problem was fixed and now regressed. Will be trying the workaround mentioned in Peter T Hayward's note. Troubling because printing was so easy before, and this kind of thing gets on my nerves quite a bit when the formerly slick and easy becomes terribly broken, especially when one's art deadline is fast approaching. :(
Seems that the udev configuration file is now 40-permissions.rules (ordering) and the syntax is moving as well, with BUS being now the more generic SUBSYSTEM So, what worked for me... ahem: SUBSYSTEM=="usb", KERNEL=="lp[0-9]", GROUP="lp" becomes: SUBSYSTEM=="usb", KERNEL=="lp[0-9]", GROUP="lp", MODE="0666" Slightly newer udev and syntax seems to have bit me and maybe many other users, but the effects are quite annoying, the printer will be automatically discovered, added to cups configuration, and promptly indicate readiness, and will defy any attempt to actually print until you add the lp group add your user to lp group, and perform this permissions modification followed by a sudo /etc/init.d/udev restart ; sudo /etc/init.d/cupsys restart. Status: /usr/lib/cups/backend/hal failed is replaced with Status: Ready: Quality control wrt printing is essential, as users get a big throbbing frustration when their printing subsystem dies because of what seems to be a trivial update of core system services. This made ubuntu look bad in front of my pen and paper gaming group, who could formerly print character sheets, and various other nerd etceterata from their windows machines to my box with minimal trouble, and now had to lug their laptops up to my room to attach usb cabling manually. -- 7.10 /usr/lib/cups/backend/hal failed https://bugs.launchpad.net/bugs/174403 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
